Performances in heating mode - Standard Unit AB
Tw= Outlet water temperature °C kWt = Heating capacity (kW). kWa = Compressor power input (kW)
The standard performances refer to a 5°C temperature difference between the water entering and leaving the plate-type heat exchanger, outdoor air with 87% relative
humidity and to operation of the unit with all the fans to top speed. A 0.44 x 10

K/W fouling factor has also been considered with the unit installed at zero meters above
sea level (Pb = 1013mbar).
The performances are declared no considering any correction due to water flow rate and water side pressure drop (gross performance).
NOTE
For air temperatures of less than 7°C, the heating capacity is declared without considering the effect of the defrosting, strictly correlated with the humidity in the outdoor air.
